We request all our artwork to be supplied as high resolution (300dpi). It is important that you prepare your PDF file in the correct way. These options must be set for commercial printing:
Resolution – Choose High Resolution
Compression Settings – For colour and greyscale this should be down sampled to 300dpi with “auto compression” set on high
Font Embedding – Should be set to “embed all fonts”
Colour needs to be set as CMYK not RGB (RGB artwork will be converted to CMYK and this could affect your colours).
